All fingers down will yield a below-the-staff D, and all fingers down with the octave key will yield a on-the-staff D as well. But the clarinet is relatively unique in that it does not. All fingers down will yield a below-the-staff G, while all fingers down with the register key will sound a middle D. So why was the clarinet build with a register key instead of an octave key? Were they any clarinets built with an octave key?
Larry's "Where does the key come from" sparked a very interesting music theory discussion, and I thought I'd dedicate a thread to another music theory discussion.

Windsong Hero Member Posts: A clarinet is not an octave instrument. It's the only woodwind in 12ths. This makes learning the clarinet a good deal more difficult for some. We have the cross-the-break to thank for that, but it allows for a much extended range.
When you blow into the clarinet's mouthpiece , the air flows through the gap between the mouthpieces lay and the thin reed tip into the clarinet. Because the reed's elastic tip is pressed by higher pressure in your mouth towards the mouthpieces surface it does bend there and reduces the air flow until it nearly completely blocks the air flowing through that gap. Then the tip of the reed swings back and opens the gap again.
This repeats very quickly so the reed is swinging. It creates a pulsed stream of air through the bore with a high frequency. This causes pressure waves through the instrument's bore travelling to the opening, the bell. The time the wave takes depends on the length of the bore.
When all tone holes are closed the column is long and the tone is low, when more and more are opened, the column gets shorter and the pitch higher, similar to shortening guitar strings.
The player's lips dampen the reed and prevent the instrument from croaking or squeaking. It is the cylindrical bore, in which the column of air swings, which results in the instrument's sound and acoustical characteristics. Details are discussed in the chapter on sound. Practically the clarinet's acoustics cause a wave of air pressure and its reflections to travel through the air column four times: First a pressure wave down the bore and out of the bell or a tone hole.
This leaves a bore with lower pressure and the reaction is a "negative" wave going back to the tip of the mouthpiece where it is reflected, travelling again to the bell where it goes out. The surrounding air then sends a positive wave back into the instrument running up to the mouthpiece's tip, where it meets a new pressure wave out of the mouth. This happens about - times per second, and as soon as a resonance is established, we hear a tone. The reed swings in exactly the frequencies the resonance of the body support and its higher mathematical multiples.
All other frequencies die away. This description is simplified, for more details and a better understanding look under the clarinet's sound. The clarinet's tone range or compass is wider than that of all other wind instruments.
All clarinets play the E E3 - some go lower and most players can reach a high c7, that means nearly 4 octaves. A bass clarinet for example can easily play everything that is possible on an Alto Sax, on a Tenor Sax and can even play a note or two lower than a Baritone Sax.
The clarinet's dynamic loudness ranges from practically inaudible ppp to a hurting fff only brass and saxophones can play louder. Other woodwinds usually will have serious difficulties beginning a phrase in ppp, not so the clarinet to be fair, saxophone players can do that, too.
It displays many characteristics you find in the human voice. It shows quite different sounds in the different registers - high, medium, low more characteristic than any other wind instrument. You can play virtually all forms of articulation with a clarinet - extremely short staccato, a perfect legato binding of notes , vibrato when it is needed, even a glissando that is changing the pitch from one tone to another without having to interrupt.
In result the clarinet is a popular instrument for us all: composers, arrangers and players, professionals and amateurs alike, playing in all kinds of ensembles. The most common material for the body is black or blackened wood mostly grenadill, an African hard wood.
On the clarinet, there are additional holes above this hole. Since there are holes in places that make them difficult to close using the fingers, keys to cover these holes are attached to the instrument. There are also keys for the holes that cannot be reached with the little finger.
The clarinet also has its own distinctive fingering. Multiple different notes can also be produced on the trombone and trumpet by changing the way in which the instrument is blown while maintaining the same fingering; on the clarinet, however, the fingering for each note is different. The two pitches are the same and are called enharmonic equivalents.
